FOLDABLE BED FRAME Filed March 2, 1946 3 Sheets-Sheet 2 IN VEN TOR. HENRY M/hf/AdFF BY M r Patented Oct. 23, 1951 FOLDABLE BED FRAME Henry Margiloff, Laurelton, N. Y., assignor to The Englander Company, Inc., Chicago, 11]., a corporation of Delaware Application March 2, 1946, Serial No. 651,490

6 Claims. 1

This invention relates to foldable bed frames and the same has particular reference to a bed frame formed of a plurality of sections hingedly connected for swinging movement thereof to dispose the same in a collapsed compact formation so as to take up a minimum of space for storage and shipment and which when disposed in collapsed relation is secured against accidental or unintentional swinging movement of the sections into bed forming relation.

The invention also has in view a bed frame of the indicated character which includes similar opposite end sections and a collapsible intermediate section hingedly connected to the end sections for movement from an aligned bed forming relation to a collapsed condition supported upon the intermediate section with the opposite end sections disposed in spaced parallel relation extending upwardly from the opposite ends of the intermediate section and adapted to receive and retain the mattress therebetween in folded relation.

The invention further has for an obiect the provision of an intermediate section of crosslegged construction which is colla sible by the spreading apart of the lower ends of the legs from a position in which the intermediate section is disposed in lon itudinal alignment with t e end sections to a relatively lower position with the end sections extending upwardly therefrom and locked in spaced apart parallel relation by the collapsing movement of the cross-legs.

The invention also comprehends the provision of cross-legs having wheels for supporting the frame thereon when in collapsed relation for facilitating rolling or movement of the frame over the supporting surface and which wheels are disposed out of contact with the supporting surface when the frame is arranged in bed forming relation with the low ends of the cross-legs supporting the intermediate section.

With the foregoing and other objects in view, reference is now made to the following specification and accompanying drawings in which the preferred embodiment of the invention is illustrated.

In the drawings:

Fig. 1 is a side view of a bed frame constructed in accordance with the invention and illustrating the same in bed forming relation.

Fig. 2 is a top plan view thereof with parts broken away to illustrate the underlying construction.

Fig. 3 is an enlarged side view thereof with the same shown in partially collapsed formation.

Fig. 4 is a similar view showing the same in fully collapsed condition.

Fig. 5 is a transverse vertical sectional View taken approximately on line 55 of Fig. 2.

Fig. 6 is a fragmentary longitudinal sectional view taken approximately on line 66 of Fi 2.

Referring to the drawings by characters of reference the bed frame consists of similar opposite end sections A and B and an intermediate section C located between the end sections and arranged in horizontal alignment therewith when disposed in bed forming relation.

The end sections A and B each comprises spaced parallel side rails 10 and an end rail l I connected between the side rails ill at the outer ends thereof and which rails are of angle iron construction arranged with the horizontal flanges I 2 disposed uppermost and the vertical flanges l3 disposed outwardly. The end sections A and B are each provided with a tubular upwardly extending U-shaped head l4 secured to the horizontal flange l2 of the end rail ll thereof. A pair of leg members I5 are also provided for each section A and B which leg members are of angle iron construction and are arranged with the side flanges l6 thereof located outermost and pivoted at their upper ends against the inner faces of the vertical flanges l3 of the side rails ID on pivot pins I! and with the transversely disposed flanges thereof located rearwardly.

The intermediate section C includes spaced parallel side rails l8 which are formed with downwardly directed terminals H3 at the opposite ends thereof. The side rails I8 and terminals l9 are of angle iron construction and are arranged with the horizontal flange 20 of the side rails 18 disposed uppermost and in horizontal alignment with the horizontal flanges I2 of the side rails ID of the end sections A and B. The flanges 20 are curved downwardly at the ends of the side rails l8 and are located outwardly at the opposite ends of the section in the terminal ends l9 thereof with the side flanges 2| of said side rails being located laterally outward. The horizontal flanges l2 of the side rails ID of the end sections A and B are cut away as at 22 with the vertical flanges l3 thereof protruding inwardly beyond the inner ends of the flanges l2 with the inwardly projecting portions of the flanges l3 disposed against the outer face of the vertical flanges of the side rails l8 of the intermediate section C and pivoted thereto on pivots 23. Link members 24 consisting of flat bars having curved inner ends are pivoted against the inner faces of the side flanges 2| of the terminal ends [9 of each of the side rails l8 of the intermediate sections C on pivots 25 with the outer ends of said links pivoted against the inner faces of the side flanges it of the leg members I on pivots 26 adjacent the pivotal connection I! of the leg members with the sections A and B respectively for effecting swinging movement of the leg members I5 from right angular relation with the end sections for supporting the same when disposed in bed forming relation to a retracted condition extending longitudinally of and in nested relation. between the flanges l2 and [3 of the side rails H3 when the sections are swung into collapsed formation.

The intermediate section C also includes a collapsible support consisting of a pair of pivotally connected crossed-legs. The crossed-legs are of general U-shaped formation consisting of side legs 21 and 28 at each side of the section, corresponding legs being connected together at their lower ends by a transversely extending bight portion 29. The side legs 21 and 28 are pivoted together by pivots 39 intermediate their ends with the opposite ends thereof located ouwardly of the side flanges 2! of the intermediate section C and connected by pins 3! to brackets 32 disposed against the inner faces of said' flanges which pins extend through and are slidable in elongated slots 33 formed in said flanges 2!. The brackets 32 are connected by a coiled contractile spring 34 for resiliently maintaining the upper ends of the pivotally connected legs 21 and 28 in inward relation adjacent the inner ends of the said slots and tensioning the outer ends of the legs 2'! and 28 against expansion thereof away from each other.

a A pair of links 35 of longitudinal arcuate formation are provided for each of the end sections A and B which links are pivoted at their outer ends on pivot pins 36 to the outer faces of the flanges l3 of the side rails l 0 adjacent the pivotal connection of the same with the intermediate section C. The other ends of the links 35 connected to the end section A are pivoted to the inner ends of the legs 2! while the links 35 connected to the end sections B have their other ends pivoted to the inner ends of the legs 28 of said cross-legs. This construction effects a collapsing or spreading apart of the lower ends of the cross-legs when the end sections A and B are swung from horizontal alignment with the intermediate section C to a collapsed relation in which the end sections extend upwardly therefrom in parallel spaced relation to dispose the side rails I 8 of the intermediate section at a relatively lower elevation whereby the bed frame takes up a minimum of space for storage and shipment when in collapsed condition.

The lower ends of the cross-legs 21 and 28 have angulated portions 38 which are disposed in parallel vertical relation when the sections are in bed forming relation, the said portions 38 being connected by the bight portion 29 which has its central portion 39 vertically offset to thereby provide U-shaped bases is for engagement with a supporting surface at each side for supporting the intermediate section C. Secured to the elevated portion 89 of the bight portion 29 of each of the cross-legs 21 and 28 are outwardly and downwardly projecting apertured lugs 4| in which are pivctally mounted caster rollers 42 disposed at an angle to the bases 40 and angulated portions 38 of the cross-legs 2'! and 28. The arrangement is such that when the lower ends, Qf

the cross-legs are swung outwardly by the collapsing or upward swinging movement of the end sections to dispose the bed frame in collapsed formation the bases 46 are swung to angular relation and the casters 42 are arranged in vertical formation for engagement with the supporting surface whereby the bed frame may be readily rolled or moved over the supporting surface when in collapsed condition.

The intermediate section C also includes transversely extending angle bars 43 secured at their opposite ends to the lower ends of the terminals it of the side rails [8 thereof to thereby rigidly connect the opposite side rails together and hold the same in lateral spaced relation.

A wire spring 4 is connected with and stretched between the side rails l2 and the end rails I I of the opposite end sections and between the side rails l8 of the intermediate section for supporting a mattress thereon and which together with the mattress is adapted to be folded and unfolded with the frame sections. The angle bars 43 are located a sufficient distance below the wire spring id to provide a clearance therebe tween so that when the weight of the mattress and a person lying thereon is imposed upon the spring the same does not contact with the said angle bars.

When the bed frame is disposed in collapsed formation by the upward swinging of the end frames and the downward collapsing of the in termediate section, the pivotal connections 25- of the links 24 with the leg members l5 are swung to a position over top dead center of the pivotalconnection 25 of the inner ends of the links 24 with the terminals l9 whereby the end sections are retained in collapsed formation against accidental or unintentional swinging thereof into bed forming relation. Furthermore, the said end sections are retained in said collapsed formation. by the weight thereof upon the intermediate section which is elevated by the outward swinging of the end sections. When in collapsed formationthe caster rollers 42 engage with the supporting surface so as to permit of the rolling movement of the bed frame thereover. The bases 49 of the cross-legs 21 and 28 are then out of engagement with the supporting surface. When, however, the bed frame is disposed in bed forming relation the caster rollers 42 are out of engagement with the supporting surface and the bases 4! support the intermediate section C.
